    I have several channels programmed in my scanner and they all worked for over a year, but now all my scanner does is squelch out. I have turned the squelch knob and nothing happens I then lock out the channel that it stopped on and it just moves up a channel and squelches out on it. I then turned my scanner off for a couple of days and unplugged it. Upon turning it back on it worked for about five minutes and at the first transmission it started squelching out all channels again. I am a first responder and emergency management coordinator and have checked my freq. and they are correct in the machine.

    The bc248clt scanner I have has the same problem . It works for a few
    minutes and then stops scanning . It has nothing to do with digital or
    analog as someone suggested . My other scanner is older (bc147xlt)
    and it works fine on the same frequencies . It seems to be related to
    the squelch because that feature does nothing when the problem
    starts . It works fine on all channels but will not scan - like the squelch
    is turned up too high . If anyone knows of a solution it will be greatly
    appreciated .

    I have the same issue and I know it is not due to anyone switching over to digital since my analog Minitor 4 pager still works and my FD is still on analog. Any help would be great.

Why won't my Realistic Pro 2020 stop scanning


You might have the squelch turned up too high so the broadcast cannot break the squelch open. Here's an instruction manual (with how-to) for your scanner. Seems easy. Also make sure you have a good antenna so you can pick up signals.

What does it mean when a channel is "locked out"?


That is a setting that is used for channels that are constantly broadcasting but you don't want to scan them because they will stop the scanner. An example is the noaa weather channel. You may want to have it on the scanner as a channel but you don't want to scan it because the scanner will stop on it all the time.

I was given a uniden police scanner and I need to know the frequencies and how to get the static out. . Thank you . Rhonda Hansen


First thing to try is to change the "squelch" setting. If you squelch is set wrong, you will hear static all the time and the scanner may not scan. Turn the squelch until you no longer hear the static and the scanner scans.

Radio shack noaa desk scanners squelch sound unit wont scan


If the squelch is on, there can't be a loud noise. Either the sqelch is completely off or you are not tuned to a station. NOAA broadcasts are continuous, not intermittent

How can i stop the squelch ive tryed turning the sqcuelch doesnt help


Plug the AC adapter into the back of the scanner and into a wall electrical outlet. Screw the antenna into the receptacle on the back of the scanner (extend the antenna to full length for best reception).

  • 2 Set the squelch level to allow signals to be heard by turning the squelch knob counterclockwise. Rotate the volume knob clockwise until you hear static. Slowly turn the squelch knob clockwise until the static noise disappears.
  • 3 Start programming frequencies into the scanner by pressing the "Manual" button.
  • 4 Press the up arrow or down arrow key until the channel you wish to program is visible on the display.
  • 5 Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.
  • 6 Press the "E" key to complete the process of entering the frequency.
  • 7 Repeat steps 3 through 6 for each additional frequency you wish to monitor.
  • 8 Press the "Scan" key to start the scanning process. The scanner stops on a channel when it detects a signal strong enough to hear over the squelch setting. Two seconds after the signal stops, the scanning process resumes.

    Turn the scanner on and volume up all the way, turn the squelch until you hear static, then turn the squelch down slowly until its silent, press scan, has it ever been programed? Just a thought. hope this helps..

    It just scans and scans it never picks anything up. No clue how to work this scanner or where to get codes for it. When you turn it on, it just scans thru all the channels but doesn't seem to pick anything...


    Sounds like either your squelch is set too high or you don't have the proper frequencies for your area programmed into the scanner. When it starts scanning turn the squelch down gradually until the scanning stops and you hear noise, then turn up slowly until it starts to scan again. If you still don't pick up anything, you probably need to reprogram the frequencies. For a list of active frequencies and systems in your area visit
    www.RadioReference.com
    or
    www.CityFreq.com
    In case you need it, here's a link to the manual for your scanner.

    Uniden UBC72XLT scanner problem.


    The cheapest solution would be to directly program the frequencies that are available in your area, usually this is public information with the exception of high security channels, you can call each location and ask them what frequency they broadcast

    Scanner wont scan


    provided you turned the squelch know and it didnt help, i would trace back from the squelch control to the first and second transistor you come to and that should be the squelch circuit. if you know how to check them with an ohm meter you can find out which one it is, if not you can just replace them both for under 5 bucks.
